Z Premium Range Support

Contacted Sony and nobody can provide me with details on the upgrade for the <br> Xperia Z phone and<br> Xperia Tablet Z tablet<br> <br> These are premium range devices.<br> <br> Nobody appears to take ownership to find anything out and communicate when questions are asked. Its always passing you onto the next person.<br> <br> Ive lost faith in a brand I followed from Ericsson days. Im thinking with Windows Mobile 10 being able to run android and OS apps, a move to Microsoft or Nokia may be the way forward given this level of service.<br> <br> Please prove me wrong and provide me AND readers with clarity on the updates. Please dont forward us to another call centre. I want to see a brand where its representatives take ownership and clients seriously.<br> <br> Please contact me where necessary via email and not telephone for record purposes.<br> <br> Feedback or the lack thereof will be shared through social networking channels. Lets make things work.
